Three Australian soldiers killed in action during World War I now have names on their headstones thanks to a volunteer research group called Fallen Diggers.
Relatives of the soldiers will attend a ceremony at the Birr Cross Cemetery near the Belgian town of Ieper on Sunday to unveil the new headstones.
Privates Henry Huntsman and Charles Eacott, from west Gippsland in Victoria, were killed by the same shell blast on September 20, 1917, during the Third Battle of Ypres (the French name for Ieper).
John "Jock" Neilson, of West Wallsend in NSW, was killed in the same battle after being stretchered off with shrapnel wounds.
Their graves, previously under headstones bearing the inscriptions "A Soldier of the Great War", were identified by researchers Andrew Pittaway and Dennis Frank of the volunteer group Fallen Diggers.
Their work, based on newly digitised World War I records of soldiers' deaths and burials, was verified by the Office of Australian War Graves.
Sunday's ceremony will be attended by the Australian Ambassador to Belgium Mark Higgie and the senior Australian Defence Force officer in Europe, Rear Admiral Allan Du Toit.
